There was extensive warm water (mainly) induced bleaching in 2010 which
was the culprit. Certainly Porites lutea on the intertidal reef flats
and shallow subtidal reefs is known to be particularly hardy.
There is a lot known about Phuket and the Andaman Sea coast of Thailand.
Barbara Brown and Niphon Phongsuan have worked there since 1979 and
published extensively. Also there is a very active scientific program at

Though the local dive masters claimed this was the best site in the area, we noted that the reef was not in great shape . In fact, much of the scleractinian coral was dead, with exception of Porites colonies (I think P. lobata). This interested me after seeing posts on the List predicting that Porites may survive climate change and rising ocean temperatures better than other genera of scleractinian corals. When we inquired as to what may have happened to kill off the coral, we were told a bleaching event occurred a couple years back. If this is true, the fact that only Porites (mostly) survived may be evidence of the current theory. I was curious to know if anyone had any pre-bleaching information on this or other sites in the area and could compare pre-bleaching verus
